I have tried recreating the repository numerous different ways, setting the hostname to "localhost" or actual machine name (QMVM-JAX-DVDB). Also disabled DHCP (based on recommendations on a post I found). I figured out that I need to kill the java.exe process that attaches to the port so I can try restarting it...but beyond that, I am having no luck with it actually running.

I forgot to mention that I had set that in the system environment vars -- that's why you don't see it above...

Setting that did nothing to resolve the issue, though.

It seems that there is a bug in the PingManager (or the underlying http code) that causes an issue attempting to connect to REPOSITORY_URL unless the network adapter has a value set for the DNS and Gateway addresses.

It doesn't seem to matter what the value is, but something had to be set or it would log the error indicating that it couldn't connect.
